C++ statements are the program elements that control how and in what order objects are manipulated. This section includes:

• Overview

• Labeled Statements

• Categories of Statements

  • Expression statements. These statements evaluate an expression for its side effects or for its return value.

  • Null statements. These statements can be provided where a statement is required by the C++ syntax but where no action is to be taken.

  • Compound statements. These statements are groups of statements enclosed in curly braces ({ }). They can be used wherever a single statement may be used.

  • Selection statements. These statements perform a test; they then execute one section of code if the test evaluates to true (nonzero). They may execute another section of code if the test evaluates to false.

  • Iteration statements. These statements provide for repeated execution of a block of code until a specified termination criterion is met.

  • Jump statements. These statements either transfer control immediately to another location in the function or return control from the function.

  • Declaration statements. Declarations introduce a name into a program. (Declarations and Definitions provides more detailed information about declarations.)
